National Captioning Institute

What National Captioning Institute does

National Captioning Institute (NCI) is a 501(c)(3) nonprofit founded in 1979 in Chantilly, Virginia, that pioneered live closed captioning for U.S. television and now delivers captioning, subtitling, translation, and audio description across broadcast, internet, VOD, education, government, and corporate verticals. Its service architecture combines human captioners (steno-captioners and voice writers) with a proprietary Automated Speech Recognition platform called CaptionSentry, which is offered in Express (client-managed), Elite (NCI-managed with 24/7 monitoring), and OnDemand (no-scheduling) tiers, and is paired with the NCIStream on-premise IP delivery device for sub-2-second latency. Supporting products include Recapd for web-display captioning, AI-powered machine translation across 800+ language combinations, and an Audio Description line partly funded by a U.S. Department of Education grant.

The company operates offices in Virginia, California, and Kentucky, with remote captioners across North and South America, and staffs scheduling, engineering, and captioning functions 24/7/365. NCI monetizes primarily through per-program/hour professional services fees for human and ASR captioning, supplemented by subscription/managed-service contracts for CaptionSentry Elite and usage-based pricing for CaptionSentry Express, with charitable donations (Friends of NCI, NCI Foundation) and government grants providing supplemental funding. Named enterprise customers include Hearst Television (sole-vendor relationship), Bloomberg, MLB Network, C-SPAN, Univision, WWE, PBS programs, and the U.S. House of Representatives, indicating a broadcast-and-government-anchored revenue mix.

Direct peers

• Caption Group: Caption Group is a partner and peer providing captioning solutions that complement NCI's offering. It competes for similar broadcast and enterprise captioning RFPs and is explicitly referenced as a 'mutual' partnership in NCI's data.
• Vitac: Vitac is widely regarded as the largest U.S. closed captioning company, providing real-time and prerecorded captioning for broadcast, cable, and online video. It is NCI's closest direct competitor across nearly identical service lines, customer segments (broadcasters, government, education), and delivery models.
• Rev: Rev offers AI- and human-powered transcription and captioning services to broadcasters, podcasters, and enterprises. It competes with NCI's ASR-based CaptionSentry on price and speed for less latency-sensitive use cases.
